Another key part of the app involves placement of water-sensitive spray cards that can be used in field locations, with optional GPS co-ordinates and comments recorded, so a map view of whole paddock coverage can be logged.

‘Following treatment, the spray cards can be photographed by SnapCard and the image cropped to the area of the card with droplets,’ Mr Emery said. ‘Actual coverage is then calculated by SnapCard and compared with the predicted coverage.’

‘This allows farmers to assess actual spray coverage and refine how they use the predictive tool. ‘
